摘要
本文根据交通标志中汉字的高度及视认距离,推算出了满足停车距离需要的最低运动视力许用值。通过对1000多名驾驶员的实测统计分析及显著性检验,证实了驾驶员的运动视力在“事故”群中平均衰减45％,无事故群平均衰减39％。说明运动状态的视力衰减严重是导致交通事故的重要原因之一。
In terms of the average height of Chinese characters on road signs and its visual distance, this paper deduced the minimum permitted distance of driver's moving sight to meet the required stopping distance for vehicle-driving. By theory of probability, more than 1000 drivers were checked for their moving sight to prove that the average decrease of Groups of Accidents around 45 percent while the average decrease of Groups of Non-accidents around 39 percent can be reached. So it can be concluded that the attenuation of driver's moving sight is one of the most important factors cause fraffic accidents.
